Asked by lijm
Bill entered three contests. The probability he will win contest A is .2, the probability that he will win Contest B is .1 and the probability that he will win the Contest C is .6. Assuming that these events are all independent of one another, what is the probability that Bill will only win Contest B (that is, he will win Contest B but will not win Contest A nor Contest C)?
I'm guessing that should be written as
P (B∩Ccomplement∩Acomplement)? For complements in this case do you subtract from one? 1- p(b) in this case?
